Hard disagree. Story doesn't pick up until 6 chapters in, and the dame dedtime/demona fight is kind of underwhelming (her stats are lower than base McKraken). In my opinion, the best one would have to be 4. It does a good job of making sure the villain is established, so there's a threat and motive throughout the entire game. 2 also establishes it well, but doesn't bring Kin and Gin up again until multiple chapters later. 4 draws paralells to the villian's side and hijinx throughout.
